Results from MD simulations are presented individually for strand 1 (s1) and strand 2 (s2). Experimental data from Duchardt et al. SD indicates the standard deviation in the experimental values. Differences and correlation coefficients calculated over nucleotides for which experimental data are available, excluding the terminal nucleotides.
